Continental facies long quartz shale horizontal well reservoir transformation method

The invention discloses a reservoir transformation method for a continental facies long quartz shale horizontal well. The reservoir transformation method comprises the following steps that the minimum horizontal principal stress and the fracture network index of a fractured target layer of the continental facies long quartz shale horizontal well are calculated; the horizontal section of the horizontal well is divided into a plurality of sections to be subjected to staged fracturing, a plurality of clusters are selected in each section to be subjected to perforation fracturing, and a staged clustering scheme is formed; determining a fracturing fluid system, a proppant material and dosage; a fracturing fluid and proppant injection process is determined, and fracturing construction of all sections is repeated; according to the method, on the basis of identifying the lithology of the reservoir, a segmented clustering scheme is optimized for the continental facies long quartz shale horizontal well reservoir, a pro
